Has anyone thought of painting a spook/spoiler with a plastic truck bedliner paint? They come in various colors. You could either keep it black, paint it the same color as the car, or go with a darker version of the car's paint. This would kind of keep it in the shadow, like the black, but give sort or a constrast to car's color. And, the paint should reduce the likelihood of chipping, cracking and abrasions. Just a thought. If it doesn't work, I am the village idiot. If it does work, I am the village genius.
